Steel tube feeding and polishing device

Abstract

The invention discloses a steel tube feeding and polishing device which comprises a bottom plate, wherein a first support plate and a second support plate are arranged on the two sides of the top endof the bottom plate; a first motor is arranged on one side of the top end of the bottom plate; a screw is arranged on the first motor; a first movable block and a second movable block are arranged onthe screw; a second motor is arranged at the top end of the first movable block; a support shaft is arranged at the top end of the second movable block; steel tube fixing shafts are arranged on the support shaft and the second motor; a support frame is arranged on one side of the top end of the bottom plate; a first hydraulic cylinder is arranged on one side of the support frame; a first hydraulictelescopic rod is arranged in the first hydraulic cylinder; a first double-shaft motor is arranged at one end of the first hydraulic telescopic rod; a first coarse polishing wheel and a first fine polishing wheel are arranged on the first double-shaft motor; a second hydraulic cylinder is arranged on the other side of the support frame; a second hydraulic telescopic rod is arranged in the secondhydraulic cylinder; a second double-shaft motor is arranged at one end of the second hydraulic telescopic rod; and a second coarse polishing wheel and a second fine polishing wheel are arranged on thesecond double-shaft motor. The steel tube feeding and polishing device has the benefits of improving the polishing efficiency and precision and lowering the labor intensity of working staff.

Description

technical field [0001] The invention relates to the field of metal processing equipment, in particular to a steel pipe feeding and grinding device. Background technique [0002] Before production, steel pipe blanks are inevitably corroded by moisture in the air to produce rust, which is difficult to remove during processing, so generally processed steel pipes still need to be derusted. In the prior art, workers generally use The hand-held cutting machine is equipped with grinding discs for rust removal and polishing. When processing grinding, the intensity of manual labor is high, and the contact between the grinding disc and the steel pipe cannot be accurately controlled, which may cause excessive grinding or no grinding at all. For example, once the grinding is too deep, the surface of the steel pipe will be damaged, causing unevenness and forming waste. If the grinding is too shallow, the rust cannot be removed, and the processing is more difficult. In addition, there is ...

[0002] Before production, steel pipe blanks are inevitably corroded by moisture in the air to produce rust, which is difficult to remove during processing, so generally processed steel pipes still need to be derusted. In the prior art, workers generally use The hand-held cutting machine is equipped with grinding discs for rust removal and polishing. When processing grinding, the intensity of manual labor is high, and the contact between the grinding disc and the steel pipe cannot be accurately controlled, which may cause excessive grinding or no grinding at all. For example, once the grinding is too deep, the surface of the steel pipe will be damaged, causing unevenness and forming waste. If the grinding is too shallow, the rust cannot be removed, and the processing is more difficult. In addition, there is also polishing and grinding by automatic grinding equipment. The existing automatic polishing and grinding The machines are all single grinding heads, the grinding efficiency is low, and the grinding accuracy is poor
